Gz for the happy news!
Wow is very wide game, and there is more than dozen of ways to earn $, just a few below:
Farm gold, then sell for cash.
(You could either play with the AH, dungeon-farm, gathering farm, grind-farm, virtually anything you feel nice for you, which do give you yellow coins enough)
Run ingame services, which are paid with either gold ingame or cash irl.
(Carry arenas, boost people in raids, CMs etc.)
Run other services, related to wow, not required to earning gold ingame
(Writing Combat Routines on the forum here, for example, resell gold)
Its all about personal behavior, the gold earning schemes are changing every few months, sometimes days, but only people are left the same
A nice start point for you is spending one hour in the
Success Stories section for some ideas.
Then invest the same time, or probably bit more in the section below it -
Ban Section - Ban Reports, including the subsection
Discussions (no Ban Reports here)
There is tons of questions answered there, which may or may not rise in your head.
Good luck!
